Use the Faucet to Get Testnet Tokens

In order to interact with the Topos and Incal subnets, tokens are required to pay the minimal gas fees on these testnets. A faucet exists to allow developers to access tokens for development purposes.


To use the Faucet, you must have an address to send the tokens to. We recommend using MetaMask as your wallet, and suggest that you first follow the guide on how to add the Topos and Incal subnets to MetaMask.

The faucet is a simple web application that allows you to request tokens for a given address. It is located at

If it has been less than 24 hours since the address has requested funds, you will see an error message:

If the token allocation is successful, the application will report that:
